What TPC Group does

TPC Group is a privately held, Houston-based petrochemical company specializing in the processing of crude C4 hydrocarbons, the largest independent processor of this feedstock in North America with more than 80 years of operating history. The company separates and upgrades raw C4 streams sourced from ethylene crackers into six integrated product lines: butadiene (approximately 35% of North American supply), butene-1 (largest North American capacity), polyisobutylene including proprietary HRPIB and the newly launched PIBplus™ epoxidized PIB technology, di-isobutylene (largest North American producer), and fuel products such as MTBE and raffinates. Its technology base is anchored by the OXO-D™ oxidative dehydrogenation process, commercially operated for more than 40 years and jointly developed with UOP/Honeywell, which enables on-purpose butadiene production as the industry shifts to lighter cracker feedstocks. Houston Operations alone exceeds 1.5 billion pounds of combined annual production capacity on a 256-acre Gulf Coast site.

The company serves B2B industrial customers in synthetic rubber, fuels, lubricant additives, plastics (polyethylene co-monomers), and surfactants via a horizontal segmentation approach, with quote-based bulk pricing and multi-year contracts. Distribution is multimodal and pipeline-anchored: more than 230 miles of pipeline along the U.S. Gulf Coast complemented by barge, ship, railcar (Union Pacific, CSX, Canadian National), truck, and ISO container export capability through the Houston facility, the 218-acre Port Neches Terminal, and the Lake Charles, Louisiana terminal. TPC Group sells directly to chemical and petroleum-based companies worldwide, with commercial operations — including sales, business management, and strategic raw material purchasing for the C4 Processing, Fuels, and Isobutylene Derivatives business units — headquartered at One Allen Center in Houston. The company completed a transformational financial restructuring in 2023, has been pursuing capacity expansion (DIB increase in 2024, debottlenecking initiatives announced in 2026 targeting ~14-19% capacity additions by 2029), and maintains third-party sustainability credentials including Responsible Care Management Systems, EcoVadis Silver, ISCC Plus, and GRI/SASB/UN Global Compact alignment.
